Addind New Datatype Into A Owl File For Furthering Using

[Guest withnodelay]

Hi all, I m actually dealing with adding into my owl file a new coordinate datatype feature. I m having problems while parsing with turtle.What I want to do is:1)Create my new datatype as follows:<!-- Spatial coord--><xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"><xsd:element name="coordinate" type="xsd:string"/></xsd:schema>2)getting my domain new type associated (owl stuff)<owlatatypeProperty rdf:ID="has_Coordinate"><rdfs:domain rdf:resource="#E47.Spatial_Coordinates"/><rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#coordinate"/></owlatatypeProperty>3)Defining the literal as my new type:<has_Coordinate rdf:datatype="http://www.w3.org/2001/XMLSchema#coordinate"> <coord>40.483890533447266,-3.36331844329834</coord></has_Coordinate>I think my problems begin in the referring namespace. Got next error while parsing with turtle: rdf:datatype specified on a node with resource value!! Any suggestion would be in advance thanks, Carlos
